so just a recap on how 2014 is going to be the year of 4's for tech.
DDR4 ram which coincidentally has a minimum stick size of 4gb
likely AM4 amd platform
USB 3.2 aka usb 4.0
pcie 4.0 (rumored)
many video games with the number 4 in them excluding the obvious yearly titles from sports
many revision 4.0 softwares and OS'
and there's likely a few more I'm forgetting like openGL/CL 4.0 or something suffice to say that this year we will be seeing many 4's thrown at us and I for one plan on building a sweet 4.0 system.
